Hex Strings - C# / C Sharp

Andy via DotNetMonster.com

Can anyone help?
I am very new to writing code in C# and am using Stardraw control to write
programs to control AV equipment. I need to send some RS-232 strings in
Hex. I have managed to send & receive everything up to 7F but over and
above that it gets encoded as 3F. Unfortunately most of the equipment I am
trying to control requires checksums that amount to more than 7F which is
giving me serious control problems.
Any help anyone can give a newbie in this language would be muchly
appreciated.

I suspect you have an encoding conflict as anything above 7F as a
character is outside the range of standard ASCII, but as Ido said a code
sample would help.
